基于改进TOPSIS灰色关联投影法的主网网架结构评价
|
摘要
针对目前主网网架结构缺少全面客观评价的现状,提出一种基于改进逼近理想解法(TOPSIS)灰色关联投影法的主网网架结构评价方法。定义归一化代数连通度指标,选取归一化代数连通度、负荷平均最短供电距离、输电网网损、电压越限节点比例、重载线路比例、电压稳定裕度指标构建主网网架评价体系;使用主客观最优组合赋权法确定各评价指标权重,并采用改进TOPSIS灰色关联投影法计算各网架的综合评分。以IEEE 118节点系统及某市级电网主网架为例进行计算分析,结果验证了所提方法能够客观有效地对主网网架结构进行评价。
Aiming at the status that there lacks comprehensive and objective evaluation of main grid structure,an evaluation method based on improved TOPSIS(Technique for Order Preference by Similarity to an Ideal Solution) grey relation projection method is proposed. The normalized algebraic connectivity index is defined,and the norma-lized algebraic connectivity,average shortest load power supply distance,power loss of transmission network,node voltage limit violation ratio,and voltage stability margin indexes are selected to construct the evaluation system of main grid structure. The combination weighting approach of subjective and objective is used to determine the weights of each index,and the TOPSIS grey relation projection method is adopted to calculate the comprehensive score of each grid. The main grid of IEEE 118-bus system and a city power grid are taken as examples to calculate and ana-lysis,and results verify that the proposed method can objectively and effectively evaluate the main grid structure.
